Inter Milan stormed into the group stage of the Europa League by thrashing UMF Stjarnan -0, but Spanish side Real Sociedad were stunned by Russian side FK Krasnodar.

Croatian striker Mateo Kovacic scored a stunning hattrick, including a majestic solo effort, as the Italians ran out 9-0 winners on aggregate, with former Southampton striker Pablo Osvaldo also finding the net.

Sociedad, however, will have to do without European football this season. The Spaniards, who drew with Manchester United in the Champions League last year, crashed out of the competition despite holding a 1-0 aggregage lead going into the last 20 minutes of their second leg against Krasnodar.
